Subject: Differences on using a coarser mesh in calculating TR noise 

In the code for evaluating TR noise, the parameter for automatic meshing (which can take values from 1 to 9 -  1 being the finest and 9 the coarsest mesh) was changed from 1 to 5 and 9.
The computation time surprisingly doesn't differ much. The maximum relative error also stays close to 6% as in the case of the finest mesh. The relative difference for two cases for a mesh
number of 5 and 9 are shown in the attachment.

The conclusion being that it is better to stick to the mesh number 1 which is the finest mesh.
